Abstract

Example embodiments generally relate to adapting a transmission via first wireless technology to avoid interference with a reception via a second wireless technology. For example, a user equipment (e.g. cell phone) can include radios operating according to first and second wireless radio technologies, which can include Long Term Evolution (LTE) and a technology using the industrial, scientific and medical (ISM) frequency band. When a priority request is asserted by a radio operating in the ISM frequency band, the LTE radio may abort a scheduled transmission when certain “transmission abort criteria” are satisfied.

Claims

1. An apparatus comprising:

a first radio configured to operate in at least a first frequency band;

a second radio configured to operate in at least a second frequency band adjacent to the first frequency band; and

a controller configured to request priority for reception at the first radio over transmission from the second radio,

wherein the second radio is further configured to abort transmission when the priority is requested and transmission abort criteria is satisfied.

2. The apparatus of claim 1, wherein the controller is disposed in the first radio.

3. The apparatus of claim 1, further comprising:

a second controller disposed in the second radio, and configured to abort transmission from the second radio when the priority is requested and the transmission abort criteria is satisfied.

4. The apparatus of claim 1, wherein the first radio is configured to operate in at least an industrial, scientific and medical (ISM) frequency band.

5. The apparatus, of claim 1, wherein the second radio is configured to operate in compliance with one or more long-term evolution (LTE) specifications.

6. The apparatus of claim 5, wherein the transmission abort criteria is associated with a physical uplink shared channel (PUSCH) transmission defined in the one or more LTE specifications.

7. The apparatus of claim 6, wherein arrival of a transport block satisfies the transmission abort criteria.

8. The apparatus of claim 6, wherein completion of channel coding satisfies the transmission abort criteria.

9. The apparatus of claim 6, wherein the transmission abort criteria comprises a coding rate threshold, and the transmission abort criteria is satisfied when a coding rate of a data PUSCH transmission applying transmission time interval (TTI) bundling is below the coding rate threshold.

10. The apparatus of claim 6, wherein the transmission abort criteria comprises a delay threshold, and the transmission abort criteria is satisfied when retransmission of an aborted data PUSCH transmission applying semi-persistent scheduling (SPS) is below the delay threshold.

11. A method for avoiding interference in an apparatus configured for wireless communication, the method comprising:

scheduling reception at a first radio configured to operate in at least a first frequency band;

requesting priority for reception at the first radio over transmission by a second radio configured to operate in a second frequency band adjacent to the first frequency band; and

aborting transmission from the second radio when priority is requested and transmission abort criteria is satisfied.

12. The method of claim 11, further comprising:

conducting, the scheduled reception at the first radio after aborting transmission from the second radio.

13. The method of claim 11, wherein the second radio is configured to operate in compliance with one or more long-term evolution (LTE) specifications.

14. The method of claim 13, wherein the transmission abort criteria is associated with a physical uplink shared channel (PUSCH) transmission of the one or more LTE specifications.

15. The method of claim 14, wherein arrival of a transport block satisfies the transmission abort criteria.

16. The method of claim 14, wherein completion of channel coding satisfies the transmission abort criteria.

17. The method of claim 14, wherein the transmission abort criteria comprises a coding rate threshold, and the transmission abort criteria is satisfied when a coding rate of a data PUSCH transmission applying transmission time interval (TTI) bundling is below the coding rate threshold.

18. The method of claim 14, wherein the transmission abort criteria comprises a delay threshold, and the transmission abort criteria is satisfied when retransmission of an aborted data PUSCH transmission applying semi-persistent scheduling (SPS) is below the delay threshold.

19. A non-transient computer-readable medium comprising computer-readable instructions, which when executed by a controller cause the controller to perform operations comprising:

scheduling reception at a first radio configured to operate in at least a first frequency band;

requesting priority for reception at the first radio over transmission by a second radio configured to operate in at least a second frequency band adjacent to the first frequency band; and

aborting transmission from the second radio when priority is requested and transmission abort criteria is satisfied.

20. The non-transient computer-readable medium of claim 19, the operations further comprising:

conducting the scheduled reception at the first radio after aborting transmission from the second radio.
